We're dividing 770873 by 3 
We want to figure out the number of times 770873 can be divided by 3.

On to step 1:
7 divided by 3 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Advancing to step 2:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Let's proceed to step 3:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 256.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Let's proceed to step 4:
If we divide 28 by 3, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2569.0
If we subtract 27 from 28, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Going ahead to step 5:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 25695.0
The remainder is 2 after subtracting 15 from 17.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Let's proceed to step 6:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 256957.0
If we take 21 away from 23, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 256957.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 256957.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 256957.66 and a remainder of 0.002.
